csv error returning empty result with just headers

Open rochoa opened this issue 9 years ago • 0 comments

A query like select ST_X('MULTILINESTRING((-29 -27,-30 -29.7,-36 -31,-45 -33),(-45 -33,-46 -32))') results in ERROR: Argument to X() must be a point because st_x does not support MULTILINESTRING.

While using json/default format it reports correctly the error, for some large resultsets using csv fails to report the error and returns an empty csv file with just the headers for the column names.

Important this only happens if the result set is bigger than the number of rows used in the ogr2ogr cursor and the error is triggered not in the first batch.

Expected result

400 Bad request error as the ogr2ogr failed

Current result

csv file with just a lon column header

Note: Newer versions of gdal/ogr2ogr might have fixed the issue.
